Hi, I'm Joris Bryon

I'm the author of this book. 

In the last 6 years my team at dexter.agency and I have helped dozens of e-commerce owners around the world make more money without having to spend more on advertising.

In this book I explain step by step how we do it. 

I don't hold anything back in this book - I explain the EXACT SAME PROCESS we use at our agency to increase our client's revenues.

I even throw in a couple of bonus resources and templates so you can hit the ground running.

I do CRO, so I know social proof works 😁
Here's some:

"As an eCommerce business owner who started out over 9 years ago, I really wish I had access to such a concise source of information back then.

This is a practical guide on how to actually execute CRO through the help of a framework coined “The Dexter Method”. In essence it’s a simple, easy to follow framework that allows you to reliably and systematically keep improving your eCommerce results. I find it one of the better frameworks out there because it really gets to the point quickly and avoids unnecessary distractions.

This is particularly good for those just starting out or those who have been at it for a while but only achieved middling results. It is easy to get overwhelmed with CRO (shiny tools, ‘advanced techniques’ etc.) but Joris wisely makes a point of reminding people along the way about sticking to the fundamentals so as to keep you on track and getting wins.”
